Question

what is the volume of a pipe that has a diameter of 8 meters and a height of 3 meters of water, round to the nearest tenth

Answer 1

The pipe is in the form of cylinder.

`\begin{gathered} d\text{ = 8 m} \\ r\text{ = 4 m} \\ h\text{ = 3 m} \end{gathered}`

The volume of the pipe is calculated as,

`\begin{gathered} \text{Volume = }\pi* r^2* h \\ \text{Volume = 3.14 }*\text{ 4}*4*3 \\ \text{Volume = 150.72 }\approx150.70m^3 \end{gathered}`

Thus the volume of water is 150.70 cubic m .
